==形态特征==
竿高8-12米,直径4-6厘米,尾梢下弯,下部挺直;节间长40-50厘米,无毛,幼时被白蜡粉,竿壁稍厚;节处无毛;分枝常自竿基第一节开始,竿下部各节常生1-3枝,近水平伸展;
其上的小枝常短缩成软刺,竿中上部各节则为多枝簇生。箨鞘早落,背面无毛,常于外侧近边缘处具1-2条淡黄绿色纵条纹,腹面有光泽,先端呈稍不对称的宽三角形或近宽拱形;
箨耳不显著,常与箨片基部相连;箨舌高约3毫米,边缘具细纤毛;箨片宿存,直立,近三角形,先端边缘内卷而成锐尖头,基部两侧边缘具纤毛,并向外稍延伸而成不明显的两箨耳;
箨片基底宽度约与箨鞘先端的宽度近相等。叶鞘近无毛;叶耳常不发达,鞘口繸毛少数而细弱;叶舌极矮,近全缘;
叶片线形,通常长9-16厘米,宽10-13毫米,上表面无毛,下表面被柔毛,先端渐尖具粗糙钻状尖头,基部近圆形或楔形。花枝未见。

锦竹 jin zhu
Culms 8–12 m, 4–6 cm in diam., basally straight, apically drooping; internodes 40–50 cm, initially thinly white powdery, glabrous; wall rather thick; nodes glabrous; branching to base.
Branches 1–3 on lower nodes, nearly horizontal; branchlets on lower nodes usually specialized into weak thorns, on middle and upper nodes many, clustered. Culm sheaths deciduous, usually with 1 or 2 pale yellow-green stripes near outer margin, glabrous, apex somewhat broadly triangular or broadly arched;
auricles inconspicuous, usually joined to base of blade; ligule ca. 3 mm, margin finely ciliate; blade persistent, erect, subtriangular, base nearly as wide as sheath apex, extending outward to form inconspicuous auricles, margin involute, apex sharp. Leaf blade linear, usually 9–16 × 1–1.3 cm, abaxially pilose, adaxially glabrous. Inflorescence unknown.
* Hills, around villages. Guangdong (cultivated), Sichuan.
Bambusa subaequalis differs from B. indigena by its more slender culms with longer internodes, glabrous nodes, inconspicuous culm sheath auricles, and narrower leaf blades.

==产地生境==
产四川。生于丘陵地村落附近;广东省广州市已有栽培。模式标本采自广州中山大学竹园(引自四川邛崃县)。
==价值==
本种竿挺直而坚韧,粗度均匀,宜作棚架、农具柄等用材。
==辨析==
本种与乡土竹B. indigena Chia et H. L. Fung相似,不同之处在于本种竿壁较之稍薄,节间较长,节处无毛,箨耳不显著,叶片较窄。
